7. 7 LibreOffice Brno 2016 Conference Presentation GSoC – Writer Table Styles My name: Jakub Trzebiatowski (ubap) My mentors: Jan Holešovský Yousuf Philips Miklos Vajna
8. 8 LibreOffice Brno 2016 Conference Presentation Google Summer of Code – Writer Table Styles The projects targets were to implement the following: ODF Export and Import of Table Styles Table Styles in the sidebar Table Styles dropdown menu
9. 9 LibreOffice Brno 2016 Conference Presentation ODF Export and Import of Table Styles The UNO API had to be implemented Table Styles are exported as a <table:table- template> element The following elements are exported as in ODF specs background, body, even-columns, even-rows, first-column, first-row, last-column, last-row, odd- columns, odd-rows Six extra properties exported in “loext” namespace first-row-even-column, last-row-even-column, first-row-end-column, first-row-start-column, last- row-end-column, last-row-start-column
10. 10 LibreOffice Brno 2016 Conference Presentation ODF Export and Import of Table Styles
11. 11 LibreOffice Brno 2016 Conference Presentation Table Styles in the Styles and Formatting sidebar The sidebar is implemented but not yet fully finished Allows to: Browse the styles and filter applied styles Apply a style Update a style Hide a Style Currently applied style is highlighted
12. 12 LibreOffice Brno 2016 Conference Presentation Table Styles in the Styles and Formatting sidebar The dialog to edit properties of a Table Style is missing Table Styles dropdown menu The dropdown menu is still not implemented
13. Infrastructure for defining toolbars via .ui (Glade) files Szymon Kłos (eszka) Mentors: Jan Holešovský Samuel Mehrbrodt
14. Introduction Currently available: classic toolbars and sidebar New implementation mocups
15. Goals Rich and dynamic layout of toolbars UI easy to modify using graphical tool – Glade (no coding needed) Switching between classic and new mode Content depending on the context Layout according to screen/window size
16. Results Tabbed Contextual groups (Heiko’s concept) Contextual single toolbar
17. First steps Notebookbar as a child window – below toolbars... Loading different .ui files in each module Sfx2 slot mechanism .uno:Notebookar
18. Popup conversions Some popups were able to work only in the sidebar It was needed to create controllers for them and register in the modules After conversion they can be used in toolbars, Notebookbar and other places Examples: underline, character spacing, number format popups
19. Horizontal panels for Impress Important Impress features are animations and slide transitions and should be accessible from Notebookbar Reused sidebar panels as single horizontal widgets
20. Context handling New toolbar implementation should provide context dependent content Marks in the .ui files e.g.: context-Table, context-any Tabbed implementation shows additional tabs when user pointed table or picture Heiko’s concept contains static part and group which is replaced in some contexts STATIC PART CONTEXT DEPENDENT
21. Priorities for widgets Mechanism providing access to all buttons when window is to small to show whole content Widgets can have assigned priorities Groups are collapsed, small arrow is showed instead Content in the popup
22. Icon size customization I added possibility to change icon size in the Notebookbar and also Sidebar That feature is available in the Options From menubar: Tools > Options > View
23. Multiple implementations We had a lot of concepts Changing the implementation requires just a reload of another .ui file Added switch in the menubar New implementations can be added in the officecfg/registry/data/org/openoffice/Office/UI/Notebookbar.xcu <node oor:name="Tabbed" oor:op="replace"> <prop oor:name="Label"> <value xml:lang="en-US">Tabbed</value> </prop> <prop oor:name="File"> <value>notebookbar_tabbed.ui</value> </prop> <prop oor:name="HasMenubar"> <value>true</value> </prop> </node>
24. Toolbar modes Option to switch between Notebookbar and classic toolbars was needed We had the single toolbar but haven’t any option for easy activation Added entry in the menubar to choose the toolbar mode Entries in the officecfg (.xcu) Separate modes for each module
25. What’s next?
26. Customization Description in the XML files Transformation to .ui files ? Possibility to modify by user <bar:tab id=”tHome” text="Home"> <bar:group id=”gClipboard” text=”Clipboard”> <bar:item href=".uno:Paste" size=”big”/> <bar:grid> <bar:row> <bar:item href=".uno:Cut" size=”tiny”/> </bar:row> <bar:row> <bar:item href=".uno:Copy" size=”tiny”/> </bar:row> </bar:grid> </bar:group> <bar:separator/> </bar:tab>
27. Extensions support Extension developers should be able to add own content to the existing implementations and/or create own implementation
28. Shortcuts Important feature for keyboard users Showing the key map ? N O S E P

30. 30 LibreOffice Brno 2016 Conference Presentation Redesigning the Template Manager Akshay Deep Mentors: Samuel Mehrbrodt Yousuf Philips
31. 31 LibreOffice Brno 2016 Conference Presentation New UX DESIGN IDEA FINAL IMPLEMENTATION
32. 32 LibreOffice Brno 2016 Conference Presentation Modifications: All Templates view replacing the previous Folder view Search, Application and Category filters replacing Tab design Removal of Save as Template mode Inbuilt category selection dialog Most functionalities shifted to context-menu Marking of default templates for each application Removal of remote files view Save as Template dialog Option to edit a template not in repository Several other bug fixes
33. 33 LibreOffice Brno 2016 Conference Presentation Modifications: New ‘Selected + Hover’ state in thumbnail view How to try it? Just select a template. Now hover over a selected template and an unselected template to see the difference Save as Template Bug 95402 Improve Save as Template work flow Separated this functionality from template manager Modal dialog with category selection and template naming options Bug 94131 Option to set as default
34. 34 LibreOffice Brno 2016 Conference Presentation Start Center All Templates view in Start Center with application filter Context menu for templates in start center Toggle buttons to denote selected template view
35. 35 LibreOffice Brno 2016 Conference Presentation Impress Selection Tools > Options > LibreOffice Impress > General > Start with Template Selection Enable users to select a template when Impress starts Easy means to disable the dialog on Impress startup Dialog is Enabled by default Impress Template dialog
36. 36 LibreOffice Brno 2016 Conference Presentation Emoji Toolbar Control Akshay Deep Mentors: Samuel Mehrbrodt Yousuf Philips
37. 37 LibreOffice Brno 2016 Conference Presentation Enhancement New control, developed from scratch using emojione unicode database Control available in Writer, Impress and Calc, accessible via Standard Bar Free to use any sort of widgets to facilitate the purpose Use of tabs to filter emojis based on categories Emojis appear as a grid Easy insertion, unlike special character control which uses a modal dialog as of version 5.2 Font support (Removal of tofu char)
38. 38 LibreOffice Brno 2016 Conference Presentation Font dependent control i.e. not all fonts support them Unlike svg or png emoji, these emoji are glyphs of a particular unicode sequence How it looks now
39. 39 LibreOffice Brno 2016 Conference Presentation Further Enhancements The foundation for this enhancement has been built now. Further improvements have been proposed like: Filtering of unsupported glyphs Removal of duplicate glyphs (multicolor emoji are treated as duplicate glyph) as multicolor glyphs are not supported by any font support for svg emoji, etc. For further insights, refer to: https://akkidevblog.wordpress.com/2016/07/23/redesigning-the-template-mana ger/ https://akkidevblog.wordpress.com/2016/08/19/emoji-toolbar-control/

41. 41 LibreOffice Productivity Suite Import Cell Styles into Calc using Orcus By Jaskaran Veer Singh Google Summer of Code 2016
42. 42 LibreOffice Productivity Suite What are Cell Styles ? Cell Styles = A set of Attributes Example :
43. 43 LibreOffice Productivity Suite What is Orcus ? Standalone Filter Library Written in C++ Multi-Threaded Started out as a Kohei Yoshida's project. Now has 4-5 active and semi-active contributors Hosted on GITLAB
44. 44 LibreOffice Productivity Suite Features of Orcus Import Filters • Open Document Spreadsheet • OOXML • XLS • Plain Text • Generic XML • Gnumeric XML Parsers • CSV • YAML • XML • JSON • CSS
45. 45 LibreOffice Productivity Suite Working of Styles import Gets to know What to read Libreoffice Side Orcus Side Low Level Parser Produces Callbacks The Xml File DocShell Orcus Interface Styles Created On Screen
46. 46 LibreOffice Productivity Suite Reasons for Using Orcus • UNO is slow with all its bells and whistles. • UNO's code for importing styles isn't very reusable. • Orcus is Time and Memory Efficient because of it's modern design and data structures.
47. 47 LibreOffice Productivity Suite What's in store for you • Predefined styles means Less Clicks, Less Annoyance. • Calc would now ship with beautiful predefined set of Styles made by our UI/UX team. • Best Part : Define your own styles !
48. 48 LibreOffice Productivity Suite An example :
49. 49 LibreOffice Productivity Suite Location of styles.xml /Path/to/installation/share/calc/styles.xml
50. 50 LibreOffice Productivity Suite Attributes that we import • Font • Fill • Cell Protection • Number Format • Alignment • Borders • Underline, Strikeout Attributes that we currently don't import • Conditional format • Various properties of Alignment • Various trivial attributes
51. 51 LibreOffice Productivity Suite What we want from you • Hold on to your seats till this functionality is available. • Use this as much as you want when it's available • Report bugs to us on bugzilla. • Report if you want any attribute to be imported which currently isn't. • Contribute to Calc and Orcus ;-)
52. 52 LibreOffice Productivity Suite Review of Sidebar and it’s functionality Susobhan Ghosh Google Summer of Code 2016 Mentors: bubli, jphilipz

Also thank you to the design team and dev channel members Thanks to the community for organizing the conference and providing this opportunity to present my work No code, just screenshots! Detailed info at my blog – https://susobhang70.github.io
54. 54 LibreOffice Productivity Suite tdf#83830: Page Deck for Writer Most used Writer Properties – just one click away!
55. 55 LibreOffice Productivity Suite tdf#89466: Properties Panel for Impress/Draw Panel developed by bubli, jphilipz and Rishabh (merged this May) – I mainly worked on bugs and improvements Added Master Slide Button, Close Master View Button Enabled same panel for Draw
56. 56 LibreOffice Productivity Suite tdf#87643: Shapes Deck & Default Shapes Panel (Draw) 10 categories – 153 shapes (Same shapes found on the shapes toolbar in Draw) More Shapes Panel (WIP) would go in the Shapes Deck below Default Shapes Panel
57. 57 LibreOffice Productivity Suite tdf#87794: Media Playback Panel in Properties Deck Now Media Playback toolbar is no longer required!
58. 58 LibreOffice Productivity Suite Other Improvements tdf#93845: Show Previews checkbox for Writer Styles tdf#90078: Import Bitmap Functionality to Area Panel
59. 59 LibreOffice Productivity Suite What now? Most panels arriving in LO 5.3 QA issues are being worked on. Use the panels, report bugs! Perhaps contribute to Sidebar development?
60. 60 Unifying LibreOffice Low Level Text Layout Unifying LibreOffice Low Level Text Layout Akash Jain (autoit)
61. 61 Unifying LibreOffice Low Level Text Layout SalLayout UniscribeLayout WinLayout GraphiteLayout ServerFontLayout GenericSalLayout CTLayout PspFontLayout GraphiteServerFontLayout PspServerFontLayout SimpleWinLayout GraphiteWinLayout MultiSalLayout Problem
62. 62 Unifying LibreOffice Low Level Text Layout Problem: complexity 3 classes on Windows, simple, OpenType and Graphite. 4 classes on Unix, OpenType, Graphite, and 2 just for PostScript printing. 1 class on macOS, but no Graphite support. Now imagine how much work is needed to add support for something as simple as user controllable font features.
63. 63 Unifying LibreOffice Low Level Text Layout Problem: inconsistency Different code paths on different platform, or even for different writing systems, with little to no code sharing. Language/writing systems support varies between platform APIs. It varies even between different versions of the same platform. Different platform APIs allow for different levels of integration.
64. 64 Unifying LibreOffice Low Level Text Layout GSoC project: idea One class to rule them all. Based mostly on the existing Unix implementation. Uses HarfBuzz for everything; OpenType, Graphite and even AAT on macOS. Font loading is still done by platform APIs, for better integration.
65. 65 Unifying LibreOffice Low Level Text Layout GSoC project: status A new class, CommonSalLayout. Naming is really hard! Code integrated with font and graphics libraries on all supported platforms. Can be switched on/off at run time. Some issues remain: There seem to be some performance regressions. Font fallback does not work on macOS. Some Graphite fonts are broken (e.g. Awami font), GenericSalLayout::ApplyDXArray() I’m looking at you! Non-SFNT (e.g. Type 1) fonts are not currently supported. Controlling font features is not yet supported. Windows XP is not supported. Code should land on master soonish.
66. 66 Unifying LibreOffice Low Level Text Layout SalLayout UniscribeLayout WinLayout GraphiteLayout ServerFontLayout GenericSalLayout CTLayout PspFontLayout GraphiteServerFontLayout PspServerFontLayout SimpleWinLayout GraphiteWinLayout MultiSalLayout feature/commonsallayout branch, and soon in master CommonSalLayout
67. 67 Unifying LibreOffice Low Level Text Layout SalLayout GenericSalLayout MultiSalLayout Post 5.3 release CommonSalLayout
